Reflective percentage on occurrence - Probability versus Work Done
I have a basic question regarding occurrence percentages. I am wondering if there is a way to reflect work done in a percentage.
Currently I am having an issue with percentages as they aren't reflective of occurrence. What do I mean well if I acheive something at a rate of 1 in 4 I have a 25% occurence and 1 in 10 a 10% occurrence.
However if I have a 0 in 4 occurrence I have 0% and if I have a 0 in 10 occurrence I have a 0% or if I have never done it before I have a 0%.
Is there a way to resolve the issue that if I have 0 in 10 I have put a lot more effort in to acheive nothing than 0 in 4 or 0 in 0. Otherwise 0 percentages could be very misleading to work and effort done and overall probability of acheving a result.
